皆さまこんにちは。わたせせいぞうです。 昨今、新型ウイルスなどの影響で世の中が暗く沈んでいますが、 僕の作品を通して皆さんの心を少しでもふわっと明るく楽しくできたらいいなって思っています。 2020年3月7日(土)に予定していたサイン会のキャンセルに合わせて撮影しました動画に端を発して、 YouTubeにて今後も皆さんとの繋がりの場をもっと作っていきたいと思っています。 落ち込んでいる時や、ちょっと元気が欲しい時に何気なくお気軽に見ていただけましたら嬉しいです。 普段製作しております漫画やイラストも同様に、皆さまが少しでも明るい気持ちになれるよう僕にできることをやっていきたいです。 動画の更新は2020年4月からを予定しております。 アップルファームスタッフ一同今後とも宜しくお願い致します。 ◆ Seizo Watase Official Site：APPLE FARM http://www.apple-farm.co.jp/ ◆ Official blog：SEIZO STATION http://www.seizo-watase.com/ ◆ Instagram：seizo.watase https://www.instagram.com/seizo.watase/?hl=ja ◆Instagram : applefarm_gallery https://www.i
